[0002] In concrete buildings, the thickness of the steel bar's protective layer is crucial to the safety and durability of the structure. Normally, it is necessary to ensure that there is an adequate protective layer between the steel bar and the concrete to prevent the steel bar from rusting and damaging, thus affecting the stability of the overall structure.

[0003] When testing the thickness of the steel bar cover, in addition to measuring the distance from the concrete surface to the nearest steel bar, it is sometimes necessary to test the spacing or width between the steel bars. This is because too small a spacing between the steel bars may lead to poor concrete filling, affecting the quality of the concrete and the bearing capacity of the structure.

[0004] A Chinese utility model patent with publication number CN210321530U discloses a tool for detecting the thickness of reinforced concrete protective layer. The tool for detecting the thickness of the concrete protective layer realizes the disassembly and replacement of the detection structure through a movable connection part on the handheld structure, thereby realizing the multi-purpose function of a handheld structure. However, the detection range of the detection structure of the tool is limited, and it is necessary to set up detection structures of various specifications according to different requirements of the reinforced concrete protective layer, which is inconvenient to carry.
